Hi Bill-

I know what you're saying but I'm trying to do the correct thing: if we use 
code from another system that is copyrighted, we should do what the 
copyright asks. In the case of VTK, there are many classes (look at the 
mutex stuff, itk::object, itk:TimeStamp, itkIndent, and dozens of others) 
that are nearly direct copies. One thing we could do is identify those 
classes that are derivations of systems with copyright, and then add the 
copyright into them on a per class basis. I choose not to do that to keep 
things uniform but that may have been a bad choice.

This goes for any algorithms/filters that other folks have written: if they 
are direct derivations of existing code with copyright, then that should be 
acknowledged in that particular class, or in some other way.

Comments? Should we talk on Friday?

Will
